installing the install manager

Hi there,
I just tried to install the new Install Manager. Installation stops right at the beginning and produces an error:
Error copying file from packed archive
C:/.../Downloads/DAZ3DIM_1.1.067_Win32.exe to C:/Program Files(x86)/DAZ 3D/DAZ3DIM1/DAZ3DIM.exe
Any idea?
Windows10 Home (64bit)

PS: Cntr + V is not working in your little "paste"-window.

What security software are you using?
mcafee - but that was never a problem...
besides: the old installmanager don't work too. I don't have the rights, it says (i'm admin on my computer) - and i cannot delate the folder daz3dim1 (same reason)
Is this an update/reinstallation on a ssytem that had DIM before?
yes
It sounds as if you may have used Run as Admistrator on the old installation, giving the folder admin rights only. You may need to run a command prompt or explorer window as administrator to delete it, then try installing again.
